Sometimes models are surprisingly smart.

Faith just doesn't have anything to do with what I'm doing as a scientist. It's nice if you can believe in God, because then you see more of a purpose in things. Even if you don't, though, it doesn't mean that there's no purpose. It doesn't mean that there's no goodness. I think that there's a virtue in being good in and of itself. I think that one can work with the world we have.

One of the nice things about math and science is it’s obvious, you get the answer or you don’t get the answer.

I did not set out to explain the extinction of the dinosaurs. I'm a particle physicist, and I was actually thinking about dark matter along with some collaborators.

When it comes to the world around us, is there any choice but to explore?

We certainly don't yet know all the answers. But the universe is about to be pried open.

I'm not creating the universe. I'm creating a model of the universe, which may or may not be true.
